"Angelina" sedum - Winter foilage

Last week at the Legacy Garden@ the Guilford Co. Ag. Center,  I found this plant with very colorful foliage for the winter months. I said I was going to try some different venues than flower & flora but they keep calling my camera for a closer look. My friend, Elaine, got a Master Gardener to help ID the plant. I really want one of these for my garden but sounds like this plant may be hard to come by.  It is a Sedum called Angelina".  I did minimal editing.  I may try some other apps later.  The LED screen was in bright sun and I did not notice the leaf at the top  but I would not have wanted to crop the image closer.  If I have a chance this winter, it would be a great picture with a little snow and the foilage peeping up above it. This web site has some interesting info about plants. http://awaytogarden.com/a-plant-id-order-sedum-angelina/
